v5.4.0-rc2

Fixed

• Private windows in more browsers. Microsoft Edge, Vivaldi, Chromium
  and the beta, dev and nightly builds of Chrome, Edge and Brave were
  recorded like any app, so an InPrivate or incognito window's titles
  were kept. They now get the URL of the front tab, as Chrome does, and
  nothing at all from a private window. Firefox forks (Zen, LibreWolf,
  Waterfox, Floorp, Developer Edition, Nightly) are handled like Firefox.
  Opera, Dia, Orion, Tor Browser, Mullvad Browser and a few others keep
  the app only, without titles, because tock cannot tell their private
  windows apart. The first time you use one of the newly supported
  browsers, macOS asks whether trackd may control it.
